Moot Court Competitions, Experimental Moot Courts and Documentary Role Plays To be an international lawyer is to perform international law behavior. As Schechner has put it, ‘Performance means: never for the first time. It means for the second to the nth time. Performance is twice-behaved behavior’ (Schechner, 1985, p. 36). Moot courts are a classical way to teach students ‘twice-behaved legal behavior’. In international law, moot court competitions have proliferated lately. However, the format of the moot court is copied rather uncritically, and not much attention is devoted to other, more reflexive theatrical means. In this article I try to open up space for such critical thinking beyond moot courts. I study moot courts as a form of performance, as a re-enactment. This perspective on moot courts allows me to focus on one of the core questions brought up in existing studies on re-enactments: who or what is re-enacted in such role plays? The equally main question is whether it is possible to reenact court cases differently. In order to answer this question, I will explore two alternative forms of reenactment of international law behavior: experimental moot courts and documentary role-plays. I examine what sort of behavior, what sort of character is restored in these two other forms of role-play.

Experimental Regulations and Regulatory Sandboxes – Law Without Order? This article discusses the key methodological shortcomings of experimental regulations and regulatory sandboxes. I argue that the poor design and implementation of these experimental legal regimes have both methodological and legal implications. The deficient design of experimental regulations and regulatory sandboxes can have three adverse effects: First, the internal validity of experimental legal regimes is limited because it is unclear whether the verified results are the direct result of the experimental intervention or other circumstances. The limited external validity of experimental legal regimes impedes the generalizability of the experiment. Second, experimental legal regimes that are not scientifically sound make a limited contribution to the advancement of evidence-based lawmaking and the rationalization of regulation. Third, methodological deficiencies may result in the violation of legal principles which require that experimental regulations follow objective, transparent, and predictable standards. I contribute to existing comparative public law and law and methods literature with an interdisciplinary framework which can help improve the design of experimental regulations and regulatory sandboxes. I draw on social science literature on the methods of field experiments to offer novel methodological insights for a more transparent and objective design of experimental regulations and regulatory sandboxes.

Teaching Legal Ethics by Non-Ethical Means – With Special Attention to Facts, Roles and Respect Everywhere in the Legal Curriculum Legal ethics may be taught indirectly, given resistance to ethics as a separate and presumably merely subjective subject. This may be done by stressing the importance of facts (as the vast majority of legal issues relate to contested facts), of professional role consciousness and of the importance of formal and informal respect for all concerned. This indirect approach is best integrated into the whole of the legal curriculum, in moot practices and legal clinics offering perceptions of the administration of legal justice from receiving ends as well. Basic knowledge of forensic sciences, argumentation and rhetoric may do good here as well. Teachers of law are to set an example in their professional (and general) conduct.

Legal Philosophy as an Enrichment of Doctrinal Research Part I: Introducing Three Philosophical Methods In this article, we discuss a particular form of interdisciplinary legal research. We focus on a discipline that may be fruitfully combined with doctrinal research, namely philosophy. The aim of this article is to give an account of the methods of philosophy that are most relevant and useful for doctrinal legal scholars. Our focus is therefore mostly on legal philosophy and the philosophical subdisciplines closely related to it, such as political philosophy and ethics. We characterize legal philosophy in three complementary ways: as an activity, as insights, and as theories. We then discuss three methods of legal philosophy: argumentation analysis and construction, author analysis and reflective equilibrium. In the practice of research these three methods are usually combined, as we will show with various examples.

Linking Legal Scenarios to Empirical Data Different legal rules can lead to the same observable outcome, making it difficult to identify the most influential rule. This article addresses this gap by focusing on how competing explanatory theories derived from a doctrinal analysis can be assessed using a methodology called process-tracing. One of process-tracing’s main uses is to link explanatory theories to empirical evidence, permitting an assessment of causal mechanisms’ practical impact in comparison to each other. This article demonstrates the potential and practical implementation of process-tracing in the context of empirical legal research. In addition to the core characteristics of process-tracing, the paper clarifies when process-tracing can add to a doctrinal analysis and the requirements which have to be met. Furthermore, the process of linking doctrinal work with empirical evidence relying on process-tracing is shown, using the example of copyright ownership in the broadcasting sector. As a result, this paper demonstrates the added value of a process-tracing analysis carried out in addition to doctrinal work, in particular the insights into industry practice it generates.

Law and Economics’ Responses to the Threat of Its Initial Success This paper starts by reviewing empirical research that threatens law and economics’ initial success. This research has demonstrated that the functioning of the law cannot be well understood based on the assumption of the rational actor and that policies which are based on this assumption are likely to be flawed. Subsequently, three responses to this criticism are discussed. Whereas the first response denounces this criticism by maintaining that the limitations attributed to the rational actor can easily be incorporated in rational choice theory, the second response welcomes the criticism as an opportunity to come up with an integrative theory of law and behavior. The third response also takes the criticism seriously but replaces the aspiration to come up with such an integrative theory by a context-sensitive approach. It will be argued that the first two responses fall short while the third response offers a promising way to go forward.

Should Jurists Take Interests More Seriously? The purpose of this article is to investigate whether the notion of an interest should be taken more seriously than the notion of a right. It will be argued that it should; and not only because it can be just as amenable to the institutional taxonomical structure often said to be at the basis of rights thinking in law but also because the notion of an interest has a more epistemologically convincing explanatory power with respect to reasoning in law and its relation to social facts. The article equally aims to highlight some of the important existing work on the notion of an interest in law.

Stumbling Blocks in Empirical Legal Research: Case Study Research This article examines the main assumptions and theoretical underpinnings of case study method in legal studies. It considers the importance of research design, including the crucial roles of the academic literature review, the research question and the use of rival theories to develop hypotheses and the practice of identifying the observable implications of those hypotheses. It considers the selection of data sources and modes of analysis to allow for valid analytical inferences to be drawn in respect of them. In doing so it considers, in brief, the importance of case study selection and variations such as single or multi case approaches. Finally it provides thoughts about the strengths and weaknesses associated with undertaking socio-legal and comparative legal research via a case study method, addressing frequent stumbling blocks encountered by legal researchers, as well as ways to militate them. It is written with those new to the method in mind.

Law and Functionalism: The Limited Function of Law This paper raises two methodological questions from a philosophical perspective: (i) what is involved in a functionalist approach to law and (ii) what should be the focus of such an approach? To answer these questions, I will take two steps with both. To begin with, I argue that Pettit’s view on functionalist approaches may be made relevant for law; functionalist accounts target a virtual mechanism that explains why a system will be resilient under changes in either the system or its environment. Secondly, I make a distinction between two interpretations of his key-concept ‘resilience’, one in mechanical, the other in teleological terms. With regard to the second question I will take two steps as well. I argue why it does not make sense to ascribe wide functions to law, followed by a plea for a limited view on the function of law. This limited view is based on a teleological understanding of the law’s resilience. I argue that these two modes are interrelated in ways that are relevant for the interdisciplinary study of law.
